Allergen, Food, Apple
Also known as: APPLE
Use
This test identifies allergen-specific IgE levels in the serum to determine sensitivity to apple allergens. Clinical relevance of detected IgE levels varies depending on concentration ranges, and may not directly correlate with clinical response or skin testing results. A comprehensive assessment considering medical history and context with potential in vivo reactions to the allergen is crucial. A negative result does not exclude the possibility of clinical allergy or anaphylaxis.
Special Instructions
Avoid multiple patient encounters prior to specimen collection. Refer to allergen specimen collection instructions for multiple allergen tests at www.aruplab.com/testing/resources/specimen.
Limitations
Concentrations of allergen-specific IgE levels do not necessarily correlate with the degree of allergic response in clinical settings. Ranges are reflective of IgE concentrations but the clinical significance and reactivity should be interpreted cautiously alongside patient history and clinical examination. IgE levels may not perfectly align with clinical symptoms, and these results should be used as part of a broader diagnostic examination by a specialist.
